Land-use suitability assessment for urban development using a GIS-based soft computing approach: A case study of Ili Valley, China

Land-use suitability assessment is an important step in land use planning for urban development. We propose a GIS-based soft computing approach (GSC), which is a combination of two multi-criteria analysis methods, i.e., the ordered weighted averaging (OWA) method and the logic scoring of preference...

We propose a GIS-based soft computing approach (GSC), which is a combination of two multi-criteria analysis methods, i.e., the ordered weighted averaging (OWA) method and the logic scoring of preference (LSP) method, to evaluate and map land-use suitability for urban development in Ili Valley, China.

Based on the final suitability results, Ili Valley was classified using five suitability levels: highly suitable, suitable, moderately suitable, marginally suitable, and not suitable. By comparing seven preference decision coefficient (α) scenarios, we determined that the area of the land that is highly suitable for urban development decreases, and the area of the marginally suitable land increases with increasing α. All of the scenarios show that approximately 32.6% of the land area is not suitable.
